SPECIFICATION forming part of Letters Patent No. 293,309, dated February 12, 1884.

I Application filed May 12, 1583. (No model.)

To all whom it may concern.:

Be it known that I, AUGUSTUS G. CHRIST- MAN, a citizen of the United States, residing at Litiz, county of Lancaster, and State of ciency of the plow, to reduce the number of pieces constituting the same.

I attain the above results by the construction shown in the accompanying drawings, which form a part of the specification, and in which corresponding parts are designated with corresponding letters.

Figure 1, Sheet 1, is an elevation of the plow divested of beam, cutter, and point on the moldboard side; Fig. 2, Sheet 1, an elevation of the land side of the plow with cutter and reversible point in place 5 Fig. 3, Sheet l,a plan ofthe plow, Fig. 4, Sheet 2, an elevation ofthe complete plow on the mold-board side; Fig. 5, Sheet 2, moldboard-side elevation of the double standard, Fig. 6, Sheet 2, land-Side elevation of the double standard; Fig. 7, Sheet 2, rear elevation ofthe standard; Fig. 8, Sheet 2, plan and edge View of the share-wing; Fig. 9, Sheet 2, plan and edge view of the cutter; Fig. 10, Sheet 2, plan and edge view of the landside; Fig. 11, Sheet 2, plan and edge view of the reversiblepoint; Figs. 12, 13, 14, andl 15, Sheet 3, sections of the reversible points at a a, b b, c c, and d d, respectively; Fig. 16,Sheet 3, perspective view of the reversible-point seat in the nose of the double standard; Fig. 17, Sheet 3, plan and elevation of the jointer complete; Fig. 1 8, Sheet 3, plan and side elevation of the friction-buttons securing the standard to jointer; Fig. 19, Sheet 3, elevation of the cutter and vmold-board ofjointer.

A represents theplow-beam, A', the ful- Crum-bolt; A2, the locking-bolt; A3., the clevis; B, handles, C, double standard; C', frontA or fulcrum standard; C2, rear or locking Standard; G3, pad for landside-handle; G4, ear `for mold-board handle; C5, raised surface ilush with landside; C, recess for reception of landside; CT, recess for reception ofpoint, G8, bolt for forcing point into its seat in the standard;

mold-board share-wing; F', lip on the same;

G, undercut portion to lap onto the sharewing, cutter, and under face of standard; G2, stop to preventthe withdrawal of the point; H, the landside; I, jointer-arm; I, jointerhead; J, mold-board and cutter standard; K, mold-board; L, cutter, M, friction-buttons; N, the pedestal for the caster-wheel; P, wheelaXis slide; Q, the wheel; R, braces from the beam to the plow; S, braces from the handles to the plow.

In construction the plow has been considerably modified, the number of pieces reduced, a better form given thereto, and facility of re-` newal thereby insured, the several parts most exposed to wear strengthened, and an independent reversible point introduced. The drawings have been so detailed that an expert will` catch the points without a lengthy description, it being sufficient to say that the point is provided witha seat, G7, in the nose cut lug, C9, opposite the bolt-hole Gs. The lug lug C, and the bolt GS, with its bevel-head, being screwed down, forces the point over against the lug, and the point, being also beveled to correspond with the lug, is thereby bound underneath the same, and as long as the bolt remains screwed up it cannot he released from the plow. The undercut portions G lap over the cutter, share-wing, and the under portion of the Standard, and is held rigidly as long as the bolt C8 is undisturbed.

receive the principal wear of the plow in use, are made small, relatively, and adjustable, and are cheaply renewed.` The landside H is not carried to the eXtreme front of the standard,

the work.

In my present arrangement of double Stand- D, the mold-board; E, mold-board cutter; F,

G, plow-point, reversible and self-Sharpening;`

ofthe double standard, which has an under- Gzof the point G is placed in contact with the `The cutter E and the share-wing F, which a recess being provided for it in the same, and Y the standard thus receives the main thrust of Ico ardI dispense with the sboe--an essential part of my patent of March 7, 1882-*very materially reducing the cost of construction, and by inaking the double standard independent of the mold-board increased facility is given to the construction of the molds inthe foundry, and more certainty as to the result of castings made therein.

In my patent of April l0, 1883, the jointer standard forms the cutter, and the mold-board is bolted to the same, whereas in my present arrangement I have the standard independent, being formed with palms, to which the cutter L and mold-board K are secured, thus gaining independent renewal of either piece.

Having shown the construction of my plow, its adaptation for renewal of parts, Snc., I desire to secure by Letters Patent the following claims thereon:

l. Ina plow, the combination, with thebeam A and handles B, of an independent double and rearwardly-bifurcated standard, C, of the section, as shown, a lug, G2, and undercut portion G, adapted to combine with lug G9 of recess GT, and by bolt G8 to be removably connected therewith, and by under-cut G to lock both cutter E and share-wing` F at their forward ends, as and for the purpose specified.

AUGUSTUS G. CHRISTM AN.
